Title: Rotating shaft mechanism, support device and folding screen apparatus
Inventor: ZHANG YAOLEI
IPC: G06F1/16
Filed: 2023-01-04
Abstract: This application provides a rotating shaft mechanism, a support apparatus, and a foldable screen device, and relates to the field of foldable screen device technologies, to resolve a problem of how to avoid exposing an internal moving part without affecting thinning of the foldable screen device. The rotating shaft mechanism includes a rotating shaft base, a shaft cover, a first swing arm, and a first drive mechanism. The shaft cover is located on a back side of the rotating shaft base, the first swing arm is rotatably connected to the rotating shaft base, and the first swing arm can rotate between an unfolded location and a folded location relative to the rotating shaft base. The first drive mechanism is connected between the first swing arm and the shaft cover, and when rotating from the unfolded location to the folded location, the first swing arm drives, by using the first drive mechanism, the shaft cover to move toward the rotating shaft base. The rotating shaft mechanism provided in this application is configured to fold a foldable screen.

Abstract: A method and circuit for calculating the instantaneous pulsating component of torque for use as a cogging feedback signal to stabilize ac motors at low frequencies. An air gap flux signal is generated by integrating the instantaneous voltage across a stator phase winding during the interval the current in that winding is zero. Pulsating torque is the product of the high pass filtered flux signal and the inverter input or dc link currant

Abstract: When machine elements (1) having a large mass shall be indexed, i.e. subjected to short, quick rotating movements, very great acceleration and deceleration forces must be transmitted via the driving means of the machine. Due to vibrations occurring, increasing the stresses on the driving means, this must be dimensioned accordingly. The present invention suggests a method and an arrangement for the compensation of the forces supplied and thus reducing the stresses occurred. This is performed by combining the indexing machine (1) element with a cam disc (6) which is affected by a number of spring-loaded (13) cam followers (9, 10), whereby the cam disc (6) has such a shape that the cam follower (9, 10) decelerate and accelerate the cam disc (6) following the desired movement I pattern of the machine element (1).

Abstract: A roller assembly includes a body (10) with a cylindrical bore (12) and rollers (14) extending lengthwise inside the bore. The rollers abut one another to form a closed circle of rollers. 
     A folded spring (18) extends diametrically across the circle of rollers with diametrically opposite ends (20,22) pressing between two adjoining rollers to wedge these rollers apart circumferentially and thus to press all the rollers against the surface (16) of the bore (12) in a "keystoning" effect with sufficient force to prevent axial movement of the rollers and to radially retain the rollers in the body. The spring is arranged to be subsequently pushed axially from the body.

Abstract: A process for the production of ferrous metals or alloys thereof in which Zn and other heavy metals are recovered from the iron-bearing flue dust and the iron dust residue is returned to the furnace. The iron bearing flue dust is first separated from the furnace flue gases and leached in an alkali metal hydroxide solution having a concentration greater than 5m and pulp density of 1 :1.5 to 1:8 at a temperature between 80°C and the boiling point of the solution. The residue is then separated from the pregnant solution and washed before it is returned to the furnace. After purification and clarification of the pregnant solution, the Zn and other heavy metals are recovered to regenerate the solution which is subsequently recycled. 
     After the iron dust residue has been washed it may be roasted with sodium carbonate at above 700 °C and leached in a caustic solution. 
     Also, the flue dust may be subject to a dilute leach the dilute leach residue then being reducted by roasting prior to the main leached step.

Abstract: Ambient or recirculated air is passed through a housing containing an evaporator core (20) and a heating core (22) by means of a blower (18). The control system comprises an automatic temperature control sensor (32) which provides a modulated vacuum control signal for a vacuum motor (40) which has an output which adjusts a biasing element in a pressure operated electrical switch (30), resulting in on/off duty cycling of an electrically energizable clutch (28) which transmits power from the vehicle engine to the cooling unit compressor (26). The percentage of time that the compressor is on versus the time off is a function of the control signal which is in turn a function ofthe ambient, in-car, and manually selected set point temperatures sensed by the sensor (32). At ambient temperatures below a predetermined minimum the control signal shuts off the compressor and places the system in a heating mode by deflecting air onto the heater core (22) via a blend door (62) operated by a vacuum motor (38) under the control of the sensor (32). The system prevents needless cooling of ambient air prior to heating, thus saving power. During the cooling mode, the cooling unit is energized only as needed to maintain the passenger compartment at the set-point temperature, thus minimizing power usage. 
     Vacuum motor (68) operates in response to engine acceleration to cut out the compressor and thereby improve vehicle performance.

Abstract: Dans des usines de production de chlorure de polyvinyle de l'air entre au cours du procede pendant les operations de production et doit etre evacue vers l'atmosphere. L'air se melange au monomere de chlorure de vinyle gazeux pendant le procede et tout le monomere de chlorure de vinyle ne peut se condenser sous forme liquide dans la recuperation normale du monomere. En consequence, le courant gazeux d'event contient des proportions appreciables de monomere de chlorure de vinyle melangees a de l'air, et dans de nombreux cas il est sature avec de la vapeur d'eau. De maniere a prelever et recuperer le monomere de chlorure de vinyle des gaz d'event avant qu'ils ne se degagent dans l'atmosphere, le courant gazeux d'event est traite en contre-courant avec un courant de solvant liquide qui absorbe le monomere de chlorure de vinyle et ce dernier est separe du solvant par application de chaleur et il est condense sous forme de chlorure de vinyle liquide, le solvant simple etant recycle vers la phase d'absorption. Le solvant utilise comme absorbant est une chaine ramifiee d'hydrocarbure aliphatique sature contenant huit atomes de carbone et compose essentiellement de 2,2,4-trimethyle pentane. Ce solvant permet de reduire la teneur de chlorure de vinyle des gaz evacues vers l'atmosphere jusqu'a moins de cinq et meme moins de une partie par millions en volume. Son utilisation permet de controler les emissions de vapeur du solvant avec les gaz d'event de maniere telle qu'ils ne soient pas nocifs pour l'environnement. Son utilisation assure egalement que l'alimentation normale de vapeur dans l'usine fournit la chaleur necessaire pour separer du solvant le monomere de chlorure de vinyle absorbe.
